1.0 INTRODUCTION

• The WBW range provides accurate, fast and versatile general

purpose weighing scales with check-weighing functions.

• There are three series within the range- WBW-M, WBW and WBWa.

• The WBW-M scales are configured at the factory for compliance with EN 45501, OIML R-76. They have different capacities and readabilities from the standard WBW series.

• The WBW series are similar to the WBWa series except the WBW scales are usually set for metric units, whereas for the WBWa series are usually set for imperial units. However, the user

can change the setting as explained in section 13.2.

• All have stainless steel weighing platforms on an ABS plastic base assembly which is sealed to IP 65, making it water-proof.

• All scales have sealed keypads with colour coded membrane switches and the displays are large easy to read liquid crystal type displays (LCD) supplied with a backlight. The scales can be supplied with an optional rear display.

• The scales include automatic zero tracking, audible alarm for preset weights and semi-automatic tare.

WARNING: The WBW-M scales should not be calibrated by the user. Calibration of the scales may make it illegal to use the scales. The scales are sealed to prevent unauthorised access to the circuit boards inside the scale. Any modifications done to the mechanisms inside by breaking the security seals may make it illegal to use the scale. If the seals are broken or tampered with, the scale needs to be re-verified by an authorised certification body and re-sealed, before it is used legally. Contact your local metrology standards office for further assistance.

Operators Manual

• The scales should not be placed in a location that will reduce the accuracy.

• Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning vents.

• Avoid unsuitable tables. The table or floor must be rigid and not vibrate.

• Avoid unstable power sources. Do not use near large users of electricity such as welding equipment or large motors.

• Do not place near vibrating machinery.

• Avoid air movement such as from fans or

opening doors. Do not place near open windows or air-conditioning vents.

• Keep the scales clean. Do not stack material on the scales when they are not in use.

3.3 SETTING UP

• The WBW Series comes with a stainless steel pan. Place it on the top if already not installed.

• Do not press with excessive force as this could damage the load cell inside.

• Level the scale by adjusting the four feet. The scale should be adjusted such that the bubble in the spirit level is in the centre of the level and the scale is supported by all four feet.

• Attach the power supply module to the bottom of the scale and plug into the mains.

Attach Power Supply module here

• Press the [O/I] key to start. The scale will first display the software revision, followed by a self-test.

• At the end of the self-test it will display zero weight, if the zero condition has been achieved and the weighing unit that was in use last. A stable and zero symbol indicators are also displayed.
